Study Of A New Driving Circuit Of The Electric Motor

Motor driver circuit for slight-stabilizing system is a pulse width modulation amplifier that is integrated by HIC. The 10-pin hermetic power package is adopted.The circuit can be operated from a single power supply over a wide range of voltages(16~ 100V)and 20A current output. Current limit is programmable by a single resistor. Ashutdown input turns off all four drivers of the H bridge output. The H bridge output MOSFETs are protected from thermal overloads by directly sensing the temperature of the die.
